9 Claims.

This invention relates to refrigerating receptacles, the principal object of which is to provide portable receptacles which are conveniently opened and closed, such as by a swinging cover for temporarily holding the contents of the receptacle therein, and especially by using a removable inner receptacle for such contents, the inner frame extending to a height such that means carried by the cover will contact such frame when the cover is closed.

Latching means is provided for the cover, and the receptacle is provided with handles pivoted at the ends of the main portion whereby the latter may be conveniently transferred over short distances manually While empty, or while filled with contents which may be carried by the inner receptacle, and may include in part or whole, bottles filled with liquid. A further advantage of our invention is the provision of a holder for a refrigeration material within the receptacle, and

suspended from the cover.

It is a further object of our invention to provide said holder for refrigerating material, of telescopic parts which may be readily opened for filling as needed, and which holder may be detachably mounted on the cover of the receptacle, so that the opening of the cover makes the refrigerating holder conveniently accessible for refilling. This feature of the main structure of our improvement permits filling of the main receptacle, with contents such as liquid-filled bottles; and said main receptacle may remain so filled until delivery thereof is to be made where ordered, when opening the cover then permits filling said holder with a refrigerant, after which the cover is closed and latched.

With these and other objects in view, which will be revealed as our description proceeds, our invention consists in the novel combination and arrangement of parts set forth in the following specification and accompanying drawings in which:

Figure 1 is an external front elevation of one of our portable receptacles;

Figure-2 is an end elevation of the same;

Figure 3 is a longitudinal section of such receptacle, taken in the plane indicated by the line 33 of Fig. 2, showing our preferred form and on an enlarged scale;

Figure 4 is a transverse view shown in the plane indicated by the line 44 of Fig. 3;

Figure 5 is a view similar to Fig. 4, but showing the. cover partly raised;

Figure 6 is a section taken in a plane substantially that of Fig. 3, but of a modified form of receptacle;

Figure '7 is a transverse sectional view ofthe form shown in Fig. 6 and in a plane indicated by the line '|--1 thereof, and on a larger scale;

Figure 8 is a perspective view of one of the telescopic parts of a holder detachably mountable on the cover of our receptacle and sus-, pended from such cover, and

Figure 9 is a perspective view of a slidable part 10 of said holder.

In these drawings, the main receptacle is designated by numeral 5 of which 6 is the body member and 1 the cover member hinged thereto. These members may have walls formed of a heat insulating composition as an artificial board whose edges may be joined together by metal angle members 8, and cover I hinged at one edge upon an upper edge of a corresponding wall of the main body member 6. Suitable handles I0 are provided at the ends 9 of the chest, and the cover 'I is further provided with a latch I l for securing the cover in closed relation. While such is the preferred material of the wall structure, it is not understood that our invention is by any means limited thereto, as our walls may be constructed of other materials while the refrigerating features of our invention may profitably be retained.

The recited heat insulating material may be braced for desired. strength by frame members [2 adjacent the edges of the body faces and secured thereto, as will be understood. Certainenclosing members H of metal such as flat bands may be attached to the edges of the cover I, as shown in Figs. 3 to 7 of the drawings, and protective in their character, especially for such top plate. To the inner surface of the cover I we may secure a polyhedral holder 13 comprising a pan-shaped member l4 having a perforated bottom I5, an open top from whose edges flanges are bent outwardly from its two side walls for attaching to the cover I, the member l4 having one open end for receiving therein an inner pan [6 when the cover I is swung open. Bracing strips 29 of heat insulating material are attached to the cover as shown in Figs. 4 and 5.

The main body 6 of the receptacle 5 will ordinarily rest upon a horizontal support, both when the hinged cover I is swung open, and when latched at H serves to retain the cover closed upon said main body. The refrigerating holder I3 will in its telescopic relation be suspended from one end of the cover I at a. point adjacent the cover hinges H, as indicated in Fig. 4. In this position the flanges l8 of the member l4 will take the position substantially level with the inner surface of the cover, and the depth of the pan I6 provided with the vertical walls i9, will be sufiiciently shallow to be received in the member l4 telescopically, to be retained in such relation when the cover is closed as above explained.

The pan 5 can be easily filled with refrigerating material such as carbon-dioxide (CO2) -often known by the popular term dry ice", especially effective in cooling the contents of the body 6 when the cover is closed. In assembling the holder i3, the filled pan I6 is inserted in the member ll before closing the cover, and the perforations of the bottom plate i5 gradually allow melting of the dioxide and fiow of the resulting liquid from the bottom of the holder. This process will be very slow since the liquid fiows from the inner pan down to the perforated bottom i5 before opportunity is afiorded for outflow down into the receptacle itself.

While we have described the holder l3 as a telescopic and fiat holder of small capacity, and referred to its adaptation for use with thematerial carbon-dioxide, in its solid form, as it will be clear that such solid may be molded to fit the pan l6, it is not to be understood that we are in any sense restricted to the use of this particular refrigerant material, designated in Fig. 4 by the numeral 2|, but that other refrigerant materials may be filled into the pan i6.

It will now be understood that the main re-= ceptacle 5 is not only provided with insulating walls for protection from heat, but that it is especially desired to provide an inner metallic casing 22 having an open top and of suitable dimensions to conveniently and detachably be received into the outer walls of the main body 6, the said casing comprising a frame having a bottom 23 and upwardly bent walls 24 whose end walls will be provided with openings adjacent their top edges, to serve as hand holds 25 whereby, when the cover I is swung open, the casing 22 with its contents may be readily lifted out, and either filled or refilled, prior to being returned to the main body 6.

If it is desired to fill the main receptacle with bottles containing liquids, it has been found desirable to provide a suitable bracket 26 of the general outline of the transverse form of the casing in a plane parallel to the bottom of the latter, the edges of the bracket being suitably secured to the vertical walls of the casing and properly spaced from the bottom 23. Said bracket 26 will be provided with a desired number 'of openings 21, and which may be arranged in rows if desired, the several openings being of" a size suitable for receiving therein the bottles to be stored while resting their weight upon the bottom 23. The depth of the casing 22 will be sufilcient to receive the height of the bottle used.

It will be evident that the refrigerant structure for storing bottled liquids above described,

, adapts itself readily to moving such bottled stock while retaining the same in cool temperature, by the following means of manipulation. The casing 22 may be filled with bottles, if such is the stock to be retained cool, if desired to be so filled before lifting into the receptacle 6, and both the latter, as well as the case 22, cooled before the holder I3 is filled with the refrigerant contents 2! for immediate cooling.

Our novel structure thus enables a plurality of cases 22 filled with bottles to be cooled ready for loading in the main case 6. It is also feasible to the top opening of the body member 6, as well to cool the main case interiorly before filling the metal case 22, the holder l3 being inserted last before closing and latching the cover 1. The case 22 being filled with bottles positioned in the bracket 26, is set in the main case 6 by grasping 5 the handles 25, after which the holder I3 is filled with the refrigerant 2|. As the cover is then closed, the supporting strips 29 will rest upon the inner case 22 at the point 32, in the preferred form, in Figs. 1 to 5; the advantageous pressure 10 exerted by the cover in closing against the case 22 prevents undesirable movement of the latter as will be evident.

Very little weight isadded to the case holding the stock enclosed, by the use of the holder i3 15 as described, while effectively maintaining the low temperature of ,the contents of such case 22, and for long periods of time after filling the same.

A suitable choice of heat insulating material for the walls of the main case 6 is afforded, and little go disadvantage has been found to result from the use of metal for the inner case 22 as described.

It will be obvious that an exceedingly large stock of bottles sealed and holding cooled liquids ready for transportation by any of the more or- 25 dinary means may be stored in very large chambers filled to their approximate capacity without wasting much refrigerating material, and that our structure here disclosed may make possible filling such casing, when required promptly with the cold stock, after which the cover, with its filled holder I3 is closed, and the case is ready for shipment.

It is an advantage in some uses of our structure that the inner telescopic pan i6 is remov- 5 able from the outer part H, as shown in our preferred form in Figs. 1, 2, 3, 4, 5, 8, and 9, in a direction lengthwise of the cover I and receptacle 5. We however have uses for applying the containers or holders l3 transverse of the chest 40 and cover, in the manner shown in Figs. 6 and 7 of the drawings which provide a modified form showing a mounting of the holder whose side walls are suspended from the flanges l8 which are secured to the inner surface of the-cover I, and transverse of the latter, and whereby the length of the closed holder i3 fits quite aptly between the side walls of the main body 6, when the cover 1 with its holder I3 is closed.

In either form of our complete receptacle 5, 59 the same general form of telescopic members I4 and I6 will be used, it being understood however that the relative length of the closed holder i3 as to the size and general outline of. the cover I, will remain substantially in the preferred form of Figs. 3, 4 and 5, in a plane at right angles to the relative position of such holder in the modified form of Figs. 6 and '7. 60 In either structural form however the open end of the member I6 will be limited in its movement by contact with the closed end 28 of member l4, so that a cavity results which is closed by their telescopic relation, the bottom openings 20 .serv- C5 ing the only means of air circulation from the contents of the pan [6 and the interior of the main chest 22. In the preferred form of refrigerant holder i3, it is often found advantageous to support the flanges I8 of the member 7 i4 upon supporting strips 29 of the cover, as shown in Figs. 3, 4 and 5." In thelatter case, the length of the holder l3 will be approximately one half that of the main chest or cover.

The supports 30 of Figs. .6 and 'I rest upon case 22 at point 3|, and supports 29 rest upon 22 in Figs. 3, 4 and 5, at point 32.

It is to be understood that other changes in construction may be made as may prove expedient and fall within the scope of the appended claims.
